Where does food leave the digestive system and into the circulatory system?
digestive system throw the waste and dirt from the body and nutrients enters the circulatory system through capillaries.
What is the advantage of a tubelike digestive system over a saclike digestive system?
One advantage of having a tube-like digestive tract is that digestive processes with different requirements (for example, an acidic or basic environment) can be separated within the tract.
Because food moves along the alimentary canal in a single direction, the tube can be organized into specialized compartments that carry out digestion and nutrient aborption in a step-wise fashion.
Where and when does your body digest proteins?
your body digests protein because it is an important nutrient for staying healthy. Just as it digests fat and carbohydrates
Mechanical digestion is the physical mashing and pulling apart of food like chewing your food. Chemical digestion uses acids and enzymes to chemically break down the food until it is small enough to be absorbed through the wall of the small intestine.
How do healthy food help digestion?
There are several foods that contain substances called prebiotics and probiotics. In essence, they are good bacteria that helps maintain gut health. For example, yogurt can contain these types of bacteria. Mountain High yogurt has several strains and Kefir yogurt has about 10 strains. Both of these can help improve the bacteria profile in the stomach and can help improve digestion.
What are the 3 most important parts of the digestive system?
stomach, large intestine, and small intestine- ur welcome!
The alimentary canal (also called the gastrointestinal [GI] tract) is made of several segments, some of which are mentioned in the question. The GI tract begins in the mouth, which secretes important digestive enzymes and performs mechanical digestion. Next is the esophagus, which is merely a vessel for transporting mashed up food from the mouth into the stomach. The stomach secretes acid and enzymes that continue the process of digestion. Next is the small intestine, which contains three parts: duodenum, jejunum, and ileum. Digestive enzymes are added in the duodenum by the pancreas. These enzymes act in all segments of the small intestine to aid digestion. Next is the colon, which is broken down into the ascending, transverse, descending, and sigmoid colon. The colon plays a somewhat minor role in absorption of digested particles and water. Then is the rectum and anus, which don't play a significant role in digestion or absorption, but rather contribute to continence and bowel movements.
What happens in that first step of digestion?
Mastication - chewing. Your saliva, coupled with the chewing actions of your jaw/teeth, begin the disgestion process.
How does your food get from your mouth to the throat?
The food is sort of squeezed down by the esophagus due to the contraction of smooth muscles present on the inner side of the esophagus and this contraction is actually a movement known as peristalsis.
It is just like squeezing something inside a tube or a pipe.
peristalsis
The organ that is the first major site chemical digestion?
The first major site of chemical digestion in frog is their stomach
What is the length of a large intestine in human?
it is the size of your whole hand.once you grow you're large intestine will grow.
Where does enzymatic digestion of carbohydrates take place?
there are at least 2:
amylase (made in the pancreas) breaks carbohydrates into smaller molecules called maltose.
then another enzyme called maltase breaks down the maltose into individual molecules of glucose
What are nursing interventions for indigestion?
Eliminate smells from the environment, if possible.
provide pt c ice chips, crackers, hot tea c lemon unless contraindicated.
maintain pt position in semi-fowler's to prevent aspiration.
What keeps food moving through the digestive system?
Wave-like contractions of the smooth muscle called peristalsis moves food through the digestive system.
The muscles in the lining of these organs contract and relax from above the food which pushes the food downwards. this process works even if you stand upside down. it can face the strongest force of gravity very easily.
The digestive system helps the body digest food. Bacteria in the GI tract, also called gut flora or microbiome.
How do you stimulate appetite?
This blogger identifies with this issue and offers some tips on stimulating appetite:
"In light of my experience, and because I know there are others out there who dream of one day having curves of their own, here are my own set of tips on how to deal with a loss of appetite:
- Go to the grocery store and walk down all the aisles. If you see something that makes you feel hungry, get it.
- Keep a special stash of crackers or granola bars on hand for tough days
- Have small snacks throughout the day so that making a meal doesn't seem like such a big deal. Small bags of walnuts, raisins, an apple, some cheese and crackers, a glass of chocolate milk…
- If there is a particular food you love, indulge yourself. For me it was potatoes. Mashed, boiled, baked, fried, any way I could have them. On their own or as part of a larger meal
- Eat with friends. Make a lunch or dinner date with someone else (especially if they are aware of the difficulty). Eating is a social activity, and it's easier to eat more sometimes when you're distracted and can spread it out over a longer period of time.
- Make food with friends! Even better, as the preparation and anticipation can increase appetite as well. Again, because you're committing to eating with others, it becomes harder to avoid your body's hunger.
- Give in to the fries! Or
! If it makes you hungry, eat it, as long as you can also ensure you're meeting your nutritional requirements. For me, I occasionally began eating red meat again, a little bit at a time, because my body craved those particular tastes and nutrients. Watch out for signs of anaemia. - Try some new foods. This was a hard step for me, but once I found a method that agreed with me, I was able to try new foods, as long as I was in a comfortable, supportive, unpressured environment. Stir fry, kabobs, sweet and sour veggie meatballs, spring rolls and even avocadoes have made it into my diet."
What effects does alcohol have on the esophagus?

How does an emergency alert system work?
An emergency alert system participant wears an alert mechanism around their neck and there is a base unit placed within the household. In the case of an emergency, the participant pushes the red button on the mechanism they wear, which sends an alert signal to the base unit. The base unit then contacts an operator. The base unit has a loud speaker that can be heard throughout the household, as well as a super-sensitive microphone so the operator can hear you.
